The International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) is a WHO approved “derived” classification based on the International Classification of Functioning, Disability and Health (ICF). In the interest of a streamlined, comprehensive ICF which adequately addresses all aspects of functioning across the lifespan, the relevant stakeholders have agreed to merge the two classifications back into one while completing other updates and revisions. This Resolution outlines that decision and provides additional detail about the process moving forward.
